I love these pens! Just like writing with an ultra fine Sharpie, but without the bleed through and harsh odor! I have tried both the capped version of this pen and the click and I must say, for my day to day, I like the retractable style better. it's easy to clip on my shirt collar and go, and I don't have to worry about losing my pen lid. These are my favorite pens of all time! I wish we could refill these... maybe someday, Sharpie?
